greg,
Just make a list and post it, or when one pops-up, ask. It's not rocket science and no one here will flame you in any way.
Although there are some very knowledgable folks here, no one member knows it all.
I'll get you started with a few common terms:
RB = round butt usually an RB frame is easier to conceal.
SB = square butt, sometimes preferred as easier to grip
HB = heavy barrel, that is: not a taper or "pencil" barrel.
SA = single action
DA = double action
SAO = single action only
SS = stainless steel: almost any S&W handgun where the model # begins with a 6; a 686 is a stainless gun, the 586 is the same gun in blue (or carbon steel). Stainless guns will not, to my knowledge, have a nickle finish.
I frame, J frame, K frame, N frame, X frame are the most commonly encountered S&W revolver frame sizes from smallest to largest.
Semi-Auto pistols come in first, second and third generations, and probably, with the advent of the M&P pistols, a fouth generation.
M&P = military & police.
SCSW, also known as The Book = Standard Catalog of Smith & Wesson by Supica and Nahas. This is a must-have reference, the 3rd edition is the latest
Study these, there WILL be a test!
